Liquid vs. Bar Soap

We tend to buy liquid soap for our bathroom sink. Since we share it with guests, using the same bar would kind of ick us out. But then we started thinking about how liquid must weigh more, plus there's that extra packaging. Which do you use?

Lured by perfumed scents and the promise of being more moisturizing, many women started using body wash and shower gel several years ago, while the majority of men prefer bar soap.

We think we're going to start buying only bar soap because it seems like the greener choice. (No more plastic bottles.) What do you think?
